Next-generation Sequencing03:00

Next-generation Sequencing

87.2K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Sanger Sequencing01:57

Sanger Sequencing

799.9K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Maxam-Gilbert Sequencing01:05

Maxam-Gilbert Sequencing

10.3K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

RNA-seq03:21

RNA-seq

9.1K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Ethics in Research01:56

Ethics in Research

23.7K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Genomics02:02

Genomics

35.1K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Area of Science:

  • Genetics
  • Bioethics
  • Genomic Medicine

Background:

  • Next-generation sequencing (NGS) technologies are increasingly used in clinical diagnostics and biomedical research.
  • The comprehensive data generated by NGS, including whole genome sequencing, significantly increases the likelihood of identifying incidental findings.
  • Ethical considerations surrounding incidental findings are not new but are amplified by the scale of NGS data.

Purpose of the Study:

  • To review and discuss the ethical challenges associated with next-generation sequencing (NGS) in clinical and research contexts.
  • To highlight the increased prevalence of incidental findings due to NGS and whole genome sequencing.
  • To examine the complexities of responsibility and disclosure for incidental findings, particularly in research settings.

Main Methods:

  • This is a review article, synthesizing existing literature and ethical frameworks.
  • It analyzes ethical dilemmas by comparing clinical and research applications of NGS.
  • Specific focus on public biobank research and its unique consent and confidentiality issues.

Main Results:

  • Incidental findings are more probable with NGS and whole genome sequencing compared to conventional methods.
  • Lines of responsibility for managing incidental findings are clearer in the clinical setting than in research.
  • Public biobank research involving NGS raises significant ethical questions regarding informed consent and data confidentiality.

Conclusions:

  • The ethical management of incidental findings requires careful consideration, especially in research.
  • Clearer guidelines are needed for consent, confidentiality, and disclosure in biobank research utilizing NGS.
  • Balancing research advancement with participant welfare is paramount in genomic research.
